Title: Swing down bed with double action hinge - simplifies withdrawing bed from cupboard and placing in horizontal position
Inventor: POERINK JANNES JONGE
IPC: A47C17/56
Filed: 1973-09-05
Abstract: The bedstead is supported on three legs. One leg is attached by a hinge which is co-axial with a second hinge attached to the cupboard wall which also supports the bedstead, acting as the fourth leg. Thus the bedstead can be swung upwards about its longitudinal edge and the legs and swung towards the underside. The hinge attached to the cupboard wall is also capable of rotating about a horizontal axis perpendicular to the wall so that the bedstead can now be rotated to the vertical position flat against the inner cupboard wall. The motion is reversed when the bed is needed.

Title: Continuous piece goods conveyor control system - transports data from first storage unit to second one via sensor
Inventor: VOGEL HANS DIPL ING
IPC: B65G47/50
Filed: 1974-09-14
Abstract: Destination data is fed into a unit emitting command signals each set of data being stored in a first unit (7), and then transmitted to a second one (8) on receipt of a signal from a sensor (S1) at the conveyor intake (1) reacting to the items handled (3). The command signal from the sensor and a frequency signal proportional to conveyor speed from a second sensor (S2) so control an AND-grid (11) that the data from the second storage unit is fed into an indexing register (12) in synchronism with the frequency signals. The stages of this register for the various diversion stages are each monitored by a comparator (V1, V2, VN) and when the data agrees with that from the corresponding fixed value storeage unit (M1, M2, MN) a command signal is emitted to an actuator (W1, W2, WN) diverting the respective item.

Title: Fur combing machine feed - by endless belt with roller over rounded table with suction perforations underneath
Inventor: SELBECK HANS-GUENTER DIPL ING
IPC: C14B1/00
Filed: 1974-09-26
Abstract: A loading device to feed fur pelts into rotary combing machines includes a hollow table with a rounded end facing the combing cylinder. A porous endless belt feeds the pelt to the combing cylinder. The lower section of the rounded table is perforated so that a vacuum can be applied to pull the pelt away from the combing cylinder. The end of the perforations allows the pelt to drop on a discharge conveyor. This prevents accidents caused by the attempts of an operator to free a pelt from the combing cylinder. Only one operation is reqd. from the device.

Title: Static inverter with clock pulse generator - has rectifier supplying clock pulse generator to allow high DC input voltages to inverter
Inventor: FELDMAIR LEONHARD
IPC: H02M7/48
Filed: 1975-01-24
Abstract: The static inverter has its clock pulse generator (TG)supplied via a full wave rectifier bridge (G) from a winding (W) on the output side of the static inverter (U). The time generator input is also coupled over a capacitor (k1) to the direct current side of the static inverter. The rectifier output is coupled to the generator via a smoothing capacitor, a diode and a resistor. The generator input is protected by a zener diode. The advantage of supplying the time generator from the output side of the inverter instead of from the input side lies in allowing the inverter to handle high direct input voltages.

Title: Glass cutting appts - for cutting blanks to different lengths for automobile windscreens
Inventor: KABANOW NIKOLAJ P
IPC: C03B33/04
Filed: 1975-01-31
Abstract: In a glass cutting appts. comprising a template and cooperating driven cutter mounted above a vertically adjustable glass blank supporting table, the table is also displaced longitudinally relative to the parallel sides of the template in opposite directions during each successive cut. The longitudinal displacement is controlled by a system (pick up, flip flop circuit with binary input) responsive to the position of the cutter and stops limit the displacement to equal amounts in the opposite directions. The appts. is useful for cutting out glass blanks of different lengths for front and rear windscreens of automobiles. The length of the blanks being cut in easily adjusted on a single cutting machine thus saving in space and colour costs.

Title: Fail function discriminator monitor - has regulation conversion of command and feedback signals to error signal to actuate adjusting element
Inventor: BETTEN CARL B
IPC: G05D1/00
Filed: 1975-05-16
Abstract: Each function discriminator monitor for regulation in which a command signal and a feedback signal are converted to an error signal which actuates an adjusting element. Three or more comparators respond to the reference and error signals, and produce an output signal. It indicates an anomalous condition if the path curve of the error signal as a function of the reference signal exceeds a predetermined value round about a zero error reference point. In the monitor the command signal on the line across the input of the summing amplifier passes to a formation network which converts the command signal to a reference signal.

Title: Safety device for continuous mine conveyor - has set of overhead bars to break fall of person, and shut off drive
Inventor: POHLE HELMUT
IPC: E21F13/00
Filed: 1975-05-24
Abstract: The safety device over a continuous mine conveyor for small coal or stone consists of a set of vertical protection plates each side of the feed end of the conveyor. It has a set of resilient bars extending horizontally from the top of one side, interconnected by a chain (14a). In the event of a person falling from above onto these bars, as they bend downwards they pull the chain, and a flat bar (15) is pulled sideways by it. A vertical plunger (16) with a spring (18) under it, which engages a shallow notch in the bar, is then allowed to rise when a deeper notch (21) is brought into alignment with it. This allows a blade (19) to lift and operate a microswitch (20) to shut off the drive of the conveyor.

Patent DE-2524147-A1 (DE)
Inventor: BANNASCH ULRICH DIPL ING
IPC: C04B28/14
Filed: 1975-05-30
Abstract: The process is carried out by mixing a porous aggregate with a gypsum-water slurry as binder, filling the mixture into moulds and allowing the contents of the mould to set. Now the aim is to demonstrate a method in which even the rubble and waste material occurring in relatively large quantities in the construction industry in the production and use of panels no longer has to be deposited in environmentally polluting landfill sites, but can be usefully incorporated back into the production process. For this purpose it is proposed to use as porous aggregate steam-hardened gas concrete rubble and/or gas concrete waste material which has a bulk density of 0.3 to 0.9 kg/dm<3> and has been comminuted to form chips, chip fractions having grain sizes smaller than or equal to 50 mm being screened out and the screened-out gas concrete chips being added to the mixture in a quantity such that its volume proportion in the finished lightweight construction panel is preferably 75 to 85%. <IMAGE>

Title: Disc seal for closure cap for containers - has thin, nonelastic layer and elastic compressible layer forming a lip
Inventor: DUKESS JOSEPH
IPC: B65D41/04
Filed: 1975-06-21
Abstract: A disck seal for a closure cap for containers has an outer layer and an intermediate (sic)layer (between outerlayer and container). The outer layer is relatively thin and non elastic whilst the intermediate layer is elastic and compressible so as to form a lip protruding beyond periphery of the outer layer. The intermediate layer is 12-40 times as thick as the outer layer. The seal is used for the reliably leak-proof closure of containers such as may be used to store chemicals. The material for the seal may be readily mfrd. by multi-ply ("sandwich") extension. The seal can rotate freely in the closure cap when the latter is being screwed tight so that the elastic layer is strongly compressed and makes an efficient seal.

Title: Rapid pipe join making system - uses length of heat shrinking material over ends of tubes to be connected
Inventor: LESK ADOLF
IPC: B65G53/52
Filed: 1975-06-23
Abstract: A pipe joint employs a length of heat-shrinking tubing placed over abutting pipe ends and shrunk into position. The tubing is made of a thermplastics material having the property of maintaining the shrunk condition after cooling. The pipe ends may each have a radially outwardly projecting flange and, on shrinking, the tubing embraces the mutually remote axial faces of the flanges.
